The HTML/CSS, Vue.js, Node.js, and SQL online test assesses candidates' knowledge across the whole Web stack from HTML, CSS, and Vue on the Web front-end and Node.js on the back-end to SQL for data access.
It's an ideal test for pre-employment screening. A good full-stack Node.js developer, who is using Vue for the front end, must be able to solve problems using Node.js and also to combine Vue and HTML/CSS to create dynamic and interactive user interfaces. Moreover, they must know how to write and analyze SQL queries, which are used to communicate with the database.
This online test requires candidates to solve common HTML/CSS challenges and Vue coding problems, to answer multiple-choice questions and fill in the blank questions about Node.js, and to write SQL queries that extract, combine, and manipulate data.

Every user on your website has an image avatar that is displayed when they post a comment. You want to style these images differently from other images on your site. Add a CSS class named avatar that fulfils the following requirements:
- The avatar's border is rounded, so that it appears as a circle.
- The avatar's width and height are both 150px.
- The avatar has a solid border, has a width of 2px, and be colored gray.
For example, the avatar in the template should look like:

Vue.js
Vue.js, or Vue, is a JavaScript framework for building user interfaces and single-page applications. It focuses on declarative rendering and component composition.
Directives
A directive is a special token in the markup that tells the library to do something to a DOM element. It is often the simplest way to perform a required task.
Event handling
Event-based design patterns are very common in modern applications, especially in the development of user interfaces.

Page contains an anchor element and a paragraph below it. The paragraph's visibility should be toggled by clicking on an anchor element with the following logic:
- At start, paragraph should not be visible
- After a click, paragraph should be visible
- After another click, paragraph should not be visible again
Implement the following logic by adding missing attributes to anchor and paragraph elements.

HTML/CSSHTML/CSS
HTML is the standard markup language for creating web pages. It's an essential skill for anyone creating web pages of any complexity.
HTML attributes
HTML attributes provide extra information about HTML elements. They are used to add functionality and define behaviors of HTML documents.
SQL
SQL is the dominant technology for accessing application data. It is increasingly becoming a performance bottleneck when it comes to scalability. Given its dominance, SQL is a crucial skill for all engineers.
Aggregation
An aggregate function is typically used in database queries to group together multiple rows to form a single value of meaningful data. A good programmer should be skilled at using data aggregation functions when interacting with databases.
Subqueries
Subqueries are commonly used in database interactions, making it important for a programmer to be skilled at writing them.
Indexes
The proper implementation and use of indexes are important for improving the performance of database queries.
Conditions
Conditional statements are a feature of most programming and query languages. They allow the programmer to control what computations are carried out based on a Boolean condition.
HTML5
HTML5 is now supported in all modern browsers, making it important for front-end developers to know how to use its features.
Semantic tags
HTML5 introduced semantic tags, which can greatly improve the level of automated analysis that can be done on documents, as well as improve the readability of HTML.
CSS selectors
Selectors are a programming pattern that can be used to select an element from a container. They are primarily used in technologies such as CSS and jQuery to apply styles to groups of elements.
Insertion
Even though most database insert queries are simple, a good programmer should know how to handle more complicated situations like batch inserts.
Positioning
Dynamic positioning of user interface elements depending on resolution is more important than ever in modern applications, making this important for a front-end developer.
Styling
Styling user interfaces according to the specification is a daily routine for a front-end developer.
Language
A programmer should use a language as a tool, always taking advantage of language-specific data types and built-in functions.
Joins
A normalized database is normally made up of multiple tables. Joins are, therefore, required to query across multiple tables.
Union
In mathematics, a union typically involves testing if an element exists in two or more sets. This definition also applies as an operator and function in various programming languages. As one of the most common collection operations, alongside intersection, it's an important topic for any candidate to understand.
CSS advanced
Cascading Style Sheets are the styling language of the web. Knowledge about advanced CSS features is required for seasoned front-end developers.
Constraints
Constraints are used to define rules and relationships. They are applied to a dataset. A constraint may take many forms, such as x ≤ 5 in a programming language and a NOT NULL constraint in a SQL table definition.
Database schema
A database schema defines how data is stored in a database. An SQL database uses a schema to define tables consisting of rows and columns that use fixed data types to store data. Formalizing how data is stored is the first step towards building an application or service.
Bug fixing
Everyone makes mistakes. A good programmer should be able to find and fix a bug in their or someone else's code.
Delete
The delete statement is used to delete records in a table and is one of the four basic CRUD functions (create, read, update, and delete) required for working with any persistent storage.
Update
The UPDATE statement is used to modify the existing records in a table and is one of the most used operations for working with the database.
Views
A database view is a result set that is defined by a stored query, the results of which can can also be queried. As a fundamental and widely used database construct, it's useful for candidates to understand how and when they should be used.
Animation
Animation is the process in which images or objects are manipulated to appear as if they are moving. It's a powerful effect that is important for UI designers to understand and be able to use.
Selectors
Selectors are a programming pattern that can be used to select an element from a container. They are primarily used in technologies such as CSS and jQuery to apply styles to groups of elements.
Accessibility
Accessibility refers to the design of products, devices, services, or environments for people who experience disabilities. It's important for all designers and developers to know how to optimize for people who experience disabilities.
Tables
A table stores data as rows and columns. From databases to HTML layouts, as a data structure they are ubiquitous. They are an important structure for developers to understand and know how to use.
Performance tuning
The performance of an application or system is important. The responsiveness and scalability of an application are all related to how performant an application is. Each algorithm and query can have a large positive or negative effect on the whole system.
Node.js
Node.js is a cross-platform JavaScript runtime environment for developing a diverse variety of tools and applications. It is used primarily as the back end for web applications(including the MEAN stack).
Asynchronous programming
Asynchronous programming is a programming method used to to run tasks asynchronously. Running tasks asynchronously can improve performance and allow applications to feel more responsive. As such, it's important for all programmers who need to write performant or responsive applications.
Modules
In Node.js, modules are a way to package applications into multiple pieces. As such, it's important for every developer to know how they work.
CSS layout
Cascading Style Sheets are the styling language of the web. For a front-end developer, a knowledge of CSS layouts is required.
Forms
Forms provide a method of grouping inputs and collecting user data. As such, they are important for all front end developers.
CSS basics
Cascading Style Sheets are the styling language of the web. Any good front-end developer requires a knowledge of basic CSS features.
